# 端口号
server:
  port: 8081
  
# 数据库
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root

3.启动类

// 我们这里还没有配置数据库，exclude = {DataSourceAutoConfiguration.class就是启动时不加载数据库
// @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
@Slf4j
@SpringBootApplication
public class BlogApplication {
    
    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(BlogApplication.class, args);
        String port = context.getEnvironment().getProperty("server.port");
        log.info("http://localhost:"+port);
    }
}
